[Python] I want to install a Blender add-on using a Python file but I always get a error...

I don't use blender so much and today is the first time I'm using a Python file, so I'm having trouble with it. I want to install a add-on but I need to use a Python file, okay then, I installed Python and made the file but when I try to install the add-on in Blender, this error message appears: Error
